below (8 plus 7), except for a few individuals 
in the species P. snyderi, in which it was 7 plus 
7. The dorsal spines (Table 1) were either IV 
or V, with little variation within a species. The 
soft dorsal rays ranged from 20 to 24, and they 
varied little within a species (Table 1). The 
first ray of the anal fin was always unbranched, 
followed by 1 6 to 19 branched rays (Table 2). 
PECTORAL FIN RAYS: The upper ray of the 
pectoral fin was always simple and unbranched, 
followed by 14 to 21 branched rays (Table 2). 
The variation within species usually did not 
exceed 4. 
SCALE COUNTS (Tables 3, 4, 5): The number 
of oblique rows of scales crossing the lateral line 
from rear of head to base of caudal fin rays 
ranges from 40 to 89. The range within the 
genus of the number of scales from the lateral 
line to the anus was from 10 to 25; within each 
species the variation was up to 6, though usually 
less than 4. The number of scales from the 
lateral line to the first soft dorsal ray varied from 
3 to 11 within the genus and up to 4 within 
species. The variation within a species of the 
number of scales around the caudal peduncle was 
up to 8, and the range within the genus from 
15 to 44. 
VERTEBRAE: The number of abdominal ver- 
tebrae remained constant at 10, whereas the 
number of caudal vertebrae ranged from 18 to 
22. There was practically no variation in the 
number of caudal vertebrae within a species 
(Table 6). 
BODY MEASUREMENTS: These data show more 
variation, both within and among species, than 
the meristic data, and therefore are not used at 
all. 
DENTITION: Good diagnostic characters that 
do not vary within a species are the presence or 
absence of palatine teeth. The number of canine 
teeth in the outer row of the lower jaw was 
either 6, 8, or 10. The dentition of each species 
is diagrammed in Figures 2, 3, and 4. 
Two other characters that show no variability
